I think you are very talented. There is a sensitivity in your portraits- a depth. You should focus on human subjects because I think that is where your gift really shows. #1 and #5 are fascinating. Good use of light/dark.

You are really good. How you use light is great, you protray emotion so well. I could go on, but I will say I have worked (did grunt work for) with a pro who has been is somewhat known and he couldn't do what you did with the first pic.

Awesome pics! I too went to school for a brief while for photography. Although I've switched majors (couldn't stand the art classes) I still love to take pictures, especially b&w. I really love the first 2. Great work, keep it up!
